The system advantageously allows creation of a consistent cluster-wide snapshot with minimal or no I/O delays. In an embodiment, the system provides for use of a change tracker that tracks the metadata of all the I/Os incoming to the volumes being snapped. When the system wants to create a snapshot on all sites, the change tracker is activated on each site separately for the volumes being snapped. A snapshot is then created on each of the cluster sites/backend storage arrays separately. The change trackers are then ordered to stop tracking. A snapshot fixing procedure is then initiated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Creating consistent snapshots in a virtualized environment","description":"The described system provides that backend array-based snapshots may be created separately on each site of a cluster, and then the snapshots fixed so as to be consistent and/or otherwise identical amo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9823973","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
